Obligations of IRBsDEFINITION:Institutional Review Board (IRB): any board,

committee or group formally designated by an institution to review, approve and conduct periodic review of biomedical research involving human subjects.

ICH definition: An independent body constituted of medical, scientific and nonscientific members whose responsibility it is to ensure the protection of the rights, safety and well-being of human subjects involved in a trial.

68BAN/CDR

Obligations of IRBsREGULATION: 21CFR 56Purpose:

Protect the rights and welfare of research subjects both before and during their study participation

Determine:Should the study be approved (do benefits outweigh the risks)?What constitutes adequate informed consent?

69BAN/CDR

IRB Membership & Organization

• At least five members with appropriate qualifications to review the research

• At least one member whose primary area of interest is in a nonscientific area

• At least one member who is independent of the institution/trial site

• Should not consist entirely of men or women

• A list of IRB members should be maintained

70BAN/CDR

IRB Functions• Reviews protocols, consents, and ads• Reviews amendments• Provides expedited review—i.e. minor

changes to a protocol that don’t increase risk

• Provides continuing review of trials (at least annually)

• Reviews qualifications of investigators• Has the authority to suspend research• Reviews all adverse drug reactions both

serious and unexpected

71BAN/CDR

IRB Records• Copies of research proposals/protocol (and

accompanying documentation)

• Minutes of meetings

• Correspondence

• List of members

• Written operating procedures (SOPs) for IRB

• Kept for 3 years after completion of research

72BAN/CDR

IRB: Expedited Review

An IRB may use an expedited review procedure to review minor changes in previously approved research during the period (1 year) for which the approval is authorized

Expedited review may be carried out by the IRB Chairperson or by one or more experienced reviewers designated by the IRB Chairperson from among the members of the IRB

73BAN/CDR

IRB: Expedited Review Procedures

IRB’s which use expedited review must have a method of keeping all IRB members informed of research proposals which have been approved under this procedure

FDA may restrict, suspend, or terminate an IRB’s use of expedited review when necessary to protect the rights of subjects

HIPAAHealth Insurance Portability and

Accountability Act (HIPAA)

-Enacted in 1996 to protect the security and confidentiality of electronic health information.

-Primarily directed at the health care industry, insurers and medical providers.

-Original deadline for privacy rule by Congress missed in 1999- finally published in Dec. 2000 , with a compliance date of April 14, 2003.

85BAN/CDR

HIPAALaw applies to “Covered Entities and

Business Associates” that use or disclose protected health information.

Requires the “de-identification” of individually identifiable health information, and disclosure of uses of protected health information (PHI).

Although no FDA regulation specifically addresses HIPAA, clinical research certainly deals with PHI.

86BAN/CDR

HIPAAClinical research now includes HIPAA

authorization –either in the IC directly or in a separate document, depending on institutional or IRB policy.

- must specifically give permission to use PHI for the purpose of research

- have the right to withdraw permission to use PHI

- expiration date of the authorization- suspension of access rights to study records

until study is completed.
